Navis created HIVE-3401: --------------------------- Summary: Diversify grammar for split sampling Key: HIVE-3401 URL: https://issues.apache.org/jira/browse/HIVE-3401 Project: Hive Issue Type: Improvement Components: Query Processor Reporter: Navis Assignee: Navis Priority: Trivial
Current split sampling only supports grammar like TABLESAMPLE(n PERCENT). But some users wants to specify just the size of input. It can be easily calculated with a few commands but it seemed good to support more grammars something like TABLESAMPLE(500M). -- This message is automatically generated by JIRA.
